There are only 4 wires that make the step operate correctly. These colors are the STEP harness, not the supply from the OEM as they may vary.
1. The large red is positive all the time
2. The YELLOW is only HOT when the Ignition is on
3. The White is hot thru the wall On/Off switch
4. The Brown comes from the Magnetic or door pin switch when the door is opened or closed (ground circuit)
5. The Step itself is grounded thru the large Green wire not connected thru the wire quick connect.
6. The purple is for optional exterior lights, not needed for basic step operation.
